Almighty Coach

Explosive force is self-evident for the 100-meter sprint. Although Li Dai's explosive power aura can only increase the explosive power by 10%, for a sport that can be completed within the limit of ten seconds, the increased explosive power of 10% can already be regarded as an astronomical figure.

The explosive aura is a trick for Li Dai to retain students. It is precisely because of this explosive aura that Li Dai will give the students a test before the training starts in the morning, and then record the results at that time; do it after the evening training One test, record the results. Comparing the results of the morning and evening with each other, you can show the results of Li Dai's one-day training.

Although Li Dai does not know how much of this 10% explosive power increase will ultimately result in improved speed, Li Dai can be sure that the improved performance brought by the explosive aura can be very obvious on the electronic timer. come out.

However, Chen Haiyang ’s father did not have much hope, because he knew that sports training was originally the accumulation of time. There was no shortcut on this point, and it could not be a one- or two-day crash. It ’s okay to say a month. Now that I ’ve trained for a daytime, what is the “training effect”?

"Therefore, it's just a day of training time. What effect can it produce, can it be faster than half a second? This young coach probably wants to express himself too much, and wants to retain students too. Isn't he worried that after a day of training, he has consumed so much physical energy, maybe his performance will be lower than that in the morning! "Chen Haiyang's father secretly said.

Training will consume a lot of physical strength, but the results will not be as good as when you are full of energy. Of course, Li Dai can think of it, so Li Dai let the students take a half-hour rest. For high-level professional athletes, a half-hour break is definitely not enough, but for beginners, a half-hour break is enough for them to save a 100-meter sprint.

At this time, Chen Haiyang once again stood at the starting line, and Chen Haiyang's father also stood at the end again, holding the stopwatch.

Li Dai pulled the trigger of the starting gun, Chen Haiyang burst out, and quickly began to speed up.

"How do I think the speed seems to be faster!" Running Chen Haiyang can feel it, the speed is faster than in the morning.

"1, 2, 3, 4 ..." There is no timer in the hand of Li Dai in the distance. He counts silently in his heart. At this time, he also feels a little nervous. He is worried that Chen Haiyang's results are not satisfactory. In that case, this student will not be able to stay out of ten.

"Shoot!"

Chen Haiyang's father only felt that a figure was passing by in front of his eyes, he immediately pressed the pause button on the electronic timer.

"I don't know how the ocean is doing this time." Chen Haiyang's father still looked forward to his son. He looked at the electronic timer in his hand and his expression suddenly solidified.

"How is this possible? At 12 seconds 39, am I wrong?" Chen Haiyang's father blinked vigorously and looked carefully. The digital timer showed 12 seconds 39 indeed.

"When my son did the test before, he didn't run within 12 seconds and 80 at the fastest, but now he ran for 12 seconds and 39, more than half a second faster than the morning! Did I press it earlier?" Chen Haiyang Dad recalled carefully and confirmed that he didn't make it early.

"Is it because this electronic timer is broken? Nor is it possible that if the timer is broken, it will only slow down, not fast." Chen Haiyang's father raised his head and looked at his son, Inside, he said: "Is this the progress he made in training today?"

At this time, Li Dai had walked over quickly, and he only asked him, "How are your results?"

"12 seconds 39." Chen Haiyang's father replied honestly, there was a sense of disbelief in the words.

"I remember in the morning, Chen Haiyang's score was 13 seconds 03, an improvement of 0.64 seconds. The effect of training today is very good." Although such a large improvement is the effect of explosive aura, Li Dai did not hesitate to change He took credit for it, and then he continued: "I remember that the national standard for the third-level athletes was 12 seconds and 40 seconds by hand. Now Chen Haiyang has exceeded this data. If you take the test now, you can also get a national three. Athlete ’s certificate. "

National tier three athletes' qualifications basically have no effect, at most it is a kind of affirmation of personal ability, but for ordinary beginners, national tier three athletes are also a very encouraging result.

Chen Haiyang's father hesitated for a few seconds, then suddenly said: "Coach Li, I want to let the ocean test again, do you think it works?"

Li Dai took a slight look. He knew that Chen Haiyang ’s dad did n’t believe this result, and thought it was a coincidence, so he made this kind of request, and Li Dai would not refuse to accept it. He said: "No problem, but still Let Chen Haiyang rest for ten minutes first. Continuous testing is also prone to strain the **** lines. I ’ve done some other students ’tests first.”

Li Dai looked at the form in his hand and shouted at the training ground: "Xu Qingliang, do a warm-up exercise, prepare for the test!"

Xu Qingliang came alone in the morning, and no parents came to pick up after school in the afternoon, so Li Dai could only ask him to do the test himself, and then tell his parents the results after going back.

Xu Qingliang's figure crossed from the finish line, Li Dai pressed the electronic timer, he glanced at the number above, and said: "12 seconds 42, good results. Your morning score is 12 seconds 10, today's training , You have improved by 0.68 seconds! Do n’t forget to tell your parents about your progress today. "

Next, Li Dai turned around and called the name of another classmate: "Lu Congyan, it's your turn."

……

Chen Haiyang took a break for more than ten minutes, UU read books www.uukanshu. com then stood on the starting line again.

"Everyone, prepare ..." Li Dai raised the starting gun, and with the sound of the gun, Chen Haiyang once again ran out of the starting line.

In the second test, Chen Haiyang's mentality was also relaxed a lot, and his condition was better than before, but there was only a dozen minutes away from the first test, and Chen Haiyang's physical strength had not fully recovered, so A score of 12 seconds and 51 was ran, which was 0.12 seconds slower than the first test.

Although the speed was slower than the first time, this still surprised Chen Haiyang ’s father, who ran out of unexpected results twice in a row. Chen Haiyang ’s father had to believe that Chen Haiyang really made a big difference improvement.

"I can improve my results so much in one day, this coach Li is really a god! If I didn't see it in person, if I didn't come to count in person, I definitely don't believe it!" Chen Haiyang's father's look at Li Dai has become different. A dozen minutes ago, he also felt that Li Dai was making a fuss, but now he knows that the coach Li in front of him is really capable.

"I think even coaches in sports schools do not have such a good level of training. The effect of this training is simply against the sky. No wonder this coach Li dare to promise to refund if he fails to meet the standard. It turns out that there are really two brushes, maybe really It ’s time to hand over the child to this coach Li. ”Chen Haiyang ’s father thought of this and had already made a decision in his heart.

……

Li Dai waited for the last student to leave, packed his things, and then locked the warehouse door.

"I don't know these 13 students, I will leave a few at last." Li Dai looked at the straight road in front of her, and was unavoidably confused.

"After going back, call and confirm with these parents!" Li Dai said to herself.
